- This invention relates to buildings and them inwardly through the windows to the more particularly to an improved form of interior of the room or building. mechanism for providing sunlight in those As illustrated, the reflecting mechanism portions ofabuilding normally shut off from which is located adjacent the roof of the the direct rays of the sun. building or in any other desired place where 5 An object of this invention is to provide a it will receive the rays of the sun, includes mechanism of this type, constructed and arrelatively large curved mirrors or reflecting ranged so as to reflect light from natural surfaces 7 mounted upon supporting pins 8 sources into spaces which the light rays formed on cross bars 9 which are mounted 10 would not ordinarily reach, such as the intebetween supporting brackets 10, secured to an riors of buildings or rooms, especially and extending outwardly from the building. through windows on the north side of build Each. reflecting surface 7 is so positioned that ings or windows otherwise located at such the rays of the sun are reflected by it downtimes as they are not receiving direct sunwardly past the various windows located '15 li ht. therebelow, and the curve of the reflecting 05 A further object is to provide a mechanism surface is such that the sunlight is reflected of the type set forth, constructed and ardownwardly irrespective ofthe position of ranged so as to reflect light into a building the sun shining on the surface. Additional during daylight hours irrespective of the poreflecting surfaces 11 are so associated with sition or location of the sun with respect each of the windows 6 thata portion of the th to, rays reflected from the reflecting surtaee 7 at These and other objects which will be apthe top of the building are deflected and diparent to those skilled in this particular art rected into the interior of the building are accomplished by means of the inventlon through the-associated window. 25 illustrated in the accompanying drawings", in It will, of course, be readily understood 7.5 which Figure 1 is a partial elevational View that the greater the number ofreflectin'g surof the north side of a building provided with faces 7 located adjacent the top of the builda mechanism constructed in accordance with ing, the greater intensity of light will be reone embodiment of this invention and Fig. 2 flected downwardly. along the wall of the 39 is a transverse sectional view therethrough, building. In the drawings,Ihave illustrated so taken on the lines 2-2 of Fig. 1. two of the spheroidal reflectors, but, of course, The particular embodiment of this invenany desired number may be employed for tion which has been chosen for the purpose the purpose of reflectingastill greater'intenof illustration is shown in connection with a sity or amount of light into the secondary re- 5 building 5, having windows or other openflectors 11. A simple means for directing a ings 6 which may be so located, for example, more intense light downwardly consists of a on the north side thereof that the direct rays series of globular reflectors 12, mounted upon of the sun do not reach the associated rooms. a: supporting rod 13 secured to the supporting The present invention contemplates the brackets 10, as illustrated. The result of this provision of means located on or adjacent to arrangement is the reflecting of. a large the roof of the building and formed so as to amount of sunlight downwardly along the reflect light such as the direct light from the associated wall of the building, and the desun, downwardly along the wall of the buildflection of this sunlight into the interior of ing past the windows, and this irrespective the building; For example, assume light to of the position of the sun between the hours come along a path generally indicated by a of sunrise and sunset. Reflecting surfaces line 13.. Rays of light striking the globes are located in cooperative relation to each of 12 will be reflected downwardly as indicated thewindows and in the path of a portion of generally by the lines 14 and 15. The light the light rays reflected downwardly past the following the pathway'1'4e strikes a mirror 11 windows so as to divert these rays and direct in the upper portion of the buildingand is reflected through the associated window to the interior thereof. The light following the path 15 passes the first mirror and strikes the next mirror where it is reflected into the associated room. The same is true of light striking the globular reflecting surface 7. As a result, each secondary reflecting surface or mirror 11 receives light from. each of the reflecting surfaces 7 and 12 during the entire day, and sunlight is delivered to the interior of the building irrespective of the position of the sun.

Although I have described a specific embodiment of this invention, it will be apparent that various changes, additions, omissions and substitutions can be made therein without departing from the spirit of this invention or the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. The combination of a building provided with windows or the like, of light reflecting mechanism including a convex reflecting surface arranged in a plane substantially parallel to the wall of the building for directing a light downwardly along said wall and means for directing light through said windows to the interior of said building.

2. The combination with a building provided with windows and the like, of a plurality of reflectors having convex reflecting surfaces arranged in a plane substantially parallel to the wall of said building located so as to receive sunlight during the entire day and to reflect such light downwardly along the wall of said building and means for directing said reflected light through said windows to the interior of said building.

3. The combination with a building provided with windows and the like, of a plurality of reflectors having convex reflecting surfaces. located adjacent the top of said building, said reflectors being disposed in a plane substantially parallel to the wall of said building so as to reflect sunlight downwardly along said wall during the entire day and a reflector associated with each of said windows for directing a portion of said reflectedlight to the interior of said building.

4. In a system of illumination for a building having windows therein, a stationary disc sha ed reflector having a convex reflecting sur ace mounted above said windows and outwardly from the building, said convex reflecting surface being disposed in a plane substantially parallel to the wall of the building so as to reflect rays of light downwardly along said windows, and means for deflecting said reflected rays of light through said windows.

5. In a system of illumination for a building having windows therein, a plurality of convexreflectors stationarily mounted above said windows and outwar lly from the building and having the conver surface arranged ROBERT P. HUTCHINSON.
